Proto J5124 Torque Adapter Wrench Box End Chrome

Product Description

The PROTO J5124 is a torque adapter wrench designed for precision fastener work in professional trade environments. Built with a 12-point box end head, it delivers reliable torque transfer on standard fasteners. The chrome-plated steel construction provides corrosion resistance and durability under regular shop and field use. The head measures 1-5/64 inches in diameter with a 29/64-inch thickness, and the wrench has an overall length of 2-61/64 inches. It carries an AS954E S3.8.1 designation and is noted as non-magnetic, making it suitable for use in sensitive environments. At 0.14 pounds, it is a lightweight addition to any torque-critical toolkit.

The J5124 is suited for use in industrial, mechanical, and trade service applications where fastener access is limited and a compact box end adapter is required. The 0-degree head offset angle allows for straight-line torque application in tight spaces. It is appropriate for automotive, HVAC, electrical, and general mechanical service where controlled torque application on 12-point fasteners is necessary. The tether-capable design supports use in elevated or drop-sensitive work environments.
